A furnace here does not get long stretches of rest. Homes in Indiana run heat about eight months a year, from October through May. That kind of runtime puts steady demand on the heat exchanger and the ignition system, the parts that cycle every time the burner fires. A cracked exchanger or a failing igniter tends to surface during those months rather than sitting quiet until spring. The short window when the system sits idle is brief enough that small faults carry over instead of resetting. A hard start or a burning smell on a cold morning usually points to wear that built up over the weeks before it.
Before a contractor can quote new equipment, someone has to open the panel and trace the ductwork to see what is actually there. A breaker box may or may not carry enough capacity for a heat pump. A duct run may or may not be sealed well enough to move the air a new furnace expects to push. None of that shows up from the street, and none of it can be assumed from a listing photo. Half the homes in Indiana were built in 1976 or earlier (2020-2024 ACS 5-year). That is why a walk-through comes before a number, not after it, in a home anywhere in the state.
Does where you live in Indiana put extra strain on your HVAC system?

The outdoor unit takes the brunt of whatever weather passes through. Wind can rock a condenser on its pad, hail can dent the cabinet and bend the fins that move air across the coil, and heavy rain can work into the electrical connections if the unit isn't sealed the way it should be. If your county sits high on this list, have a contractor check where the unit sits, how well it's anchored, and the condition of the cabinet itself.
In Indiana, HVAC licensing for homes is left to the counties and cities.
Check whether your county requires a license.
